Hill, 28, according to the presser will reveal "strange and disturbing" details about growing up Xenu providing a firsthand account of Scientology's "upper ranks."

Her uncle, the controversial David Miscavige oversees the church, founded in the 1950s by sci-fi writer L. Ron Hubbard who before founding the org was best known for his lurid pulp tales of “Battlefield Earth” later made into a film starring a dreadlocked Travolta.

It has long been rumored that Hubbard established the church as a wager with Astounding magazine editor John W. Campbell who wrote the oft- filmed novella "Who Goes There?" aka “The Thing (From Another World)".

Campbell is said to have told Hubbard to start his own church as a way to beat the IRS.
